Cagliari and Sampdoria drew 2-2 after a goal-laden finish on Saturday in Serie A.
Playing in Trieste because of stadium troubles in Sardinia, Cagliari went in front through Swedish midfielder Albin Ekdal in the 26th minute.
That was the lone goal until Manolo Gabbiadini equalised in the 89th when goalkeeper Michael Agazzi let the ball trickle through his legs.
Daniele Conti restored Cagliari's lead in the first minute of stoppage time with a splendid free-kick, but Gabbiadini forced a draw with a deflected shot three minutes into added time.
Livorno stayed on the tails of the Serie A leaders by earning a 0-0 draw at Genoa.
The closest either side came to scoring came when Genoa's Thomas Manfredini hit the crossbar with a header from a free-kick in the 76th minute.
Livorno, who finished third in Serie B last season, are just two points behind league leaders Napoli and Roma.
At Chievo Verona, Brazilian midfielder Maicosuel gave Udinese the lead in the opening minute but Chievo struck back through Sergio Pellissier in the 13th and Luca Rigoni earned a 2-1 win five minutes before the break.
Udinese's attempt to equalise fell short when defender Dusan Basta hit the crossbar from distance in the 72nd minute.
